Sleep After Traumatic Brain Injury

Traumatic brain injury (TBI) is an important cause of death and disability at all ages in the world. Complete functional recovery is not always complete, and, often, persistent symptoms may last for a long time. Sleep disorders and sleep-wake alterations are among the most common complications both in the acute and chronic phases after the trauma, and they may have a negative impact on daily activities and on quality of life of these patients. Sleep and sleep-wake cycle are not always carefully assessed in patients after TBI, they are overlooked, and often patients have a persistent excessive daytime sleepiness, even for years after the TBI, without receiving a proper diagnosis and treatment. Moreover, scientific evidence has been provided for the role of sleep in neuroprotection and recovery after brain injury; hence, promoting an optimal sleep function and early diagnosing and treating sleep disorders may be helpful for rehabilitation and functional recovery of patients after TBI
